However, at the time of manufacturing the automatic feeder or at the time of periodic inspection, the table is at an arbitrary rotation angle, so the appropriate angle of the table is used as the reference angle, and the reference angle data when this matches the X axis of the reference line is used. A method is used in which the data is stored in a memory and the angle data of the mounting position of each cassette is obtained from this. Conventionally, this reference angle data is obtained by measuring the rotation angle of the table with a caliper or the like, but the accuracy is not good. If the reference angle data is misaligned with respect to the reference line, the cassettes are misaligned and the chuck mechanism 5b of the robot mechanism 5 cannot accurately chuck the desired work. Therefore, it is necessary to accurately measure the misalignment angle and calibrate the angle data in the memory. The present invention has been made in view of the above, and is provided with means for indicating the reference angle of the table and means for accurately measuring the deviation angle of the reference angle of the table with respect to the reference line on the fixed side. It is an object of the present invention to provide a method for calibrating each angle data stored in the.
